Abstract
A system for identifying the location of a dipole magnetic field source below ground. The system comprises a first receiver assembly and a second receiver assembly each configured to detect the dipole magnetic field in three dimensions from a transmitter and generate antenna signals indicative of the detected dipole magnetic field. The first receiver assembly detects the dipole magnetic field from the transmitter substantially simultaneously as the second receiver assembly simultaneously detects the dipole magnetic field from the transmitter. The second receiver assembly is movable relative to both the first receiver assembly and the transmitter. A processor determines the location of the transmitter below ground based on the antenna signals generated by the first and second receiver assemblies.
